IJOCK STRUCTURE.

Application filed august 15, 192 -Seria1 1 Toi 5 81 ,968.

To all whom may concern;

Be it known thatI, JOHN B. FREYs NcnR',

a citizen of the United States,and a resident of Stamford, in the countyof Fairfield and State of Connecticut, have invented certain new anduseful Improvements in Lock Structures; and I do hereby .declarethe following to be a full, clear, andexact description of the invention,suchas will; enable others skilled in the art toiwhich' it appertains tomake and use the samelf This invention relates to improvements inlockstructures, and more particularly to s-encasing means for a cylinderlock, 'one;obj ect of the invention being to provide avshellconstruction which may be readily adapted to doors ofdifferentthickness. anchwhich shall be provided with a simple andeflicient ring construction at oneend to seat against recessed seat forthe outer end portion of the casing of a cylinder lock locatedwithinsaid shell.

With this and other objects in view, the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims. a

In the accompanying drawings:

Figure 1 is a View in elevation of a shell structure embodying myimprovements.

Figure 2 is a longitudinal sectional view showing a cylinder lock (inelevation) within the shell,

Figure 3 is an end view of the structure shown in Figure 2, and

Figure 4: is a sectional view showing a modification. v k

In the drawings, my improved lock enclosing shell is represented at 1,and a cylinder lock contained within the shell, is indie cated at 2. Theshell 1 is intended to pass through a bore in a door to enclose thecylinder and the latter may be secured to the plate of a rim latchcasing secured tothe inner side of the door in any suitable manner,while the connectingbar 3 will be caused to cooperate with the latchmechanism in manner well understood.

If desired, the enclosing shell may be made of hardened metal sothat itwill provide an eflicient armor for the cylinder look.

In order that the shell may ,be made adaptable for use in doorsofdifi'erent .thick- 1 ness, said shell is made adjustable by theprovision (or a plurality of sections 4,one or more of which'may beremoved to afford adjustment in thelength of the shell.

To form theremovable shell sections, said shell is provided withanplurali'ty of series of elongated slots 5,"between adjacent ends ofsome of which, perforations 6 are made,

andilthemetal of the shell is grooved as at i i 7 between adjacent endsof some of the slots and between the perforations 6 and the ad jacentslot ends. In this manner, the inner portionsyof, the shell are soweakened that the normally'integral ring sections are so formed that oneor more of them may be broken off'to adjust the length of theshell toaccommodate said shell to the thickness of the'door to which it is tobeapplied.

The outer end of the shell is provided with a headjforming a facing ring8. In the outer face of a door and also aflorda' prises an annularflange 9 projecting laterally from the end of the shell; a beveledportion 10 (which may be slightly curved transversely if desired)projecting from, the

flange 9 and beyond the end of the shell, and

j a circular flange 11 which projects inwardly to vthe annular flange 9and receives the head 12 of the cylinder lock 2,-the latter having aseatjon theiinner portion of the flange 9.

' In this manner, the end of the shellis made with a facing ring whichaffords a recessed seat'for the head of the cylinder lock 2.

In, the embodiment of the invention shown in Figure 4c, the outer end ofthe shell is provided with a circumferential flange 13 forming anannular head on the shell and the'inner face of the flange or head isrecessed'as at 14. A facing ring15 to engage the outer face of the doorencircles the head or flange 13 and is formed with an inwardlyprojecting flange 16 seated in the recess 14:,

and preferably permanently secured to the facing ringby brazing, weldingor soldermg or in any other suitable manner. The

inner edge portion offithe facing ring 15 i which projects beyondfthehead of the shell is made with an annular flange 17 ,the inner edge[of'which may engage the head of the shell in such position that aportion of said head shall form a seat'18 for the hea of the cylinderlock structure 2. I

It will be seen that with my improvethe casing of a rim latch, both thelock and the enclosing shell will be firmly secured to 1 elongated slotsand perforations, said shell a fixed part of the shell providing arecessed seat for the head of the cylinder lock structure and that whenthe latter is secured to the door.

Slight changes might be made in the details of construction of myinvention Without departing from the spirit of the latter or limitingits scope, and hence I do not wish to restrict myself to the precisedetails .ings, forming a normally integral removable shell section. v

3. A shell for a cylinderlock provided with a plurality of series ofopenings, each series of openings including structure,

having grooves between the openings of each series, the plurality ofseries of openings and grooves forming normally integral removable shellsections.

i 4:- A shell for a cylinder lock structure, said shell, provided at itsouter end with an annular flange, a facing ring rigid with andprojecting forwardly from said flange, said facing ring having aninwardly projecting part cooperating with the flanged end of the shellto provide a recessed seat for the head of a cylinder lock structure.

5. A shell for a cylinder lock structure, saids'hell provided at itsouter end with a head, a facing ring having a flange engagingthe'periphe'ral portion of said head, said ring projecting beyond thehead of the shell and having an annular flange concentric with the axisof the shell and cooperating with the head of the shell toform arecessed seat for the head of the cylinder lock structure.

Intestiinon'y' whereof, I have signed this specification in the presenceof two subscribing witnesses. I V g p g v JOHN B. ,FREYSINGER. WitnessesV 'f CHARLES A. BERRY,
